Frequently Asked Questions about Prima APS 10 S4S

What are the technical features of the Audison Prima APS 10 S4S Subwoofer?

The Prima APS 10 S4S Subwoofer from Audison is a technical masterpiece. It features a 10-inch (25 cm) diaphragm with a 4-ohm voice coil, optimized for enclosures with a volume of at least 10 liters. With a peak power of 800 watts and a continuous power of 400 watts, it is designed for high performance. Its electromagnetic properties, such as a BL value of 12.9 T•m and a Qts of 0.68, ensure remarkable sound quality. The Subwoofer also has specific designs like the vent openings below the spider to reduce the overall height.

What is the size of the Audison Prima APS 10 S4S and how does it affect installation?

The Audison Prima APS 10 S4S has a size of 250 mm and an ultra-flat profile of 120 mm, allowing for flexible installation. The external dimensions are A: 270 mm, B: 233 mm, C: 105 mm, and D: 88 mm. These compact dimensions make it ideal for space-saving installations in tight spaces or in vehicles with limited installation space. Its design with innovative vent openings allows it to be mounted close to the rear wall of the enclosure, enabling a practical and space-saving installation.

What materials and construction features does the Prima APS 10 S4S Subwoofer have?

The Prima APS 10 S4S Subwoofer is made from high-quality materials, such as a water-repellent treated, pressed paper cone, specifically optimized for extreme conditions. The massive motor assembly uses high-density flux ferrite and is optimized using FEM to handle high power and displacement. Additionally, the special geometry of the cone, dust cap, and basket allows for long linear displacement with minimal installation depth.

How does bass enhancement work in the Audison Prima APS 10 S4S?

The Audison Prima APS 10 S4S is optimized for bass enhancement with the AP F8.9 Bit Amplifier featuring integrated DSP. The Subwoofer utilizes the bass enhancement function and the parametric equalizer of the DSP to precisely boost and adjust the bass. This allows for fine-tuning of the bass frequencies, resulting in a detailed and powerful bass reproduction, particularly evident in applications with sealed enclosures starting from 10 liters in volume.

What electrical parameters should I consider when operating the AproPOS APS 10 S4S?

When operating the Prima APS 10 S4S Subwoofer, you should pay attention to the electrical parameters such as impedance, which is at 4 ohms, and the Re, which is 3.7 ohms. These parameters are crucial for matching with the Amplifier. The Subwoofer requires an Amplifier that can handle this impedance to achieve maximum performance. Equally important is the voice coil with a diameter of 60 mm, which is essential for the required load capacity and power output to avoid distortion.

What Thiele-Small parameters does the Audison Prima APS 10 S4S have and what do they mean?

The Audison Prima APS 10 S4S features important Thiele-Small parameters, including a Qts of 0.68, a Vas of 39.62 liters, and a Qes of 0.75. These parameters are critical for the acoustic behavior of the Subwoofer. Vas describes the equivalent air volume, and a higher Qts value indicates suitability for sealed enclosures. These values should be considered in enclosure design to ensure the best possible sound and efficient use of the Subwoofer.

What type of enclosure is optimal for the Audison Prima APS 10 S4S Subwoofer?

The Prima APS 10 S4S Subwoofer is designed for optimal use in sealed enclosures, starting from a volume of 10 liters. Thanks to the construction with a water-repellent cone and the specially adjusted acoustic parameters such as Fs of 28.5 Hz and an Xmax of 12.6 mm, it achieves the best performance in these types of enclosures regarding sound quality and bass power. The cone's design allows for a long linear excursion, which is particularly advantageous in sealed enclosure types.

How is the Audison Prima APS 10 S4S correctly installed?

The correct installation of the Prima APS 10 S4S requires that the dimensions of 270 mm in width and 233 mm in height be considered. When mounting near a rear wall of the enclosure, the ventilation openings below the spider must be taken into account, which allow for additional ventilation of the voice coil and can prevent errors. The use of the included steel grille and plastic seals ensures stability and protection during installation. The installation should take place in a volume of at least 10 liters to achieve maximum performance.

What is the maximum displacement of the Audison Prima APS 10 S4S Subwoofer and what does this mean?

The maximum mechanical displacement Xmech of the Prima APS 10 S4S Subwoofer is 18 mm, while the linear displacement Xmax is 12.6 mm. This means that the Subwoofer is capable of handling large movements of the diaphragm, resulting in powerful bass reproduction. The linear displacement allows for undistorted playback of the bass, especially at high volumes. The robust construction ensures that the Subwoofer operates without sound loss and distortion, even under maximum load.

How does the cone material of the Prima APS 10 S4S affect the sound?

The cone material used in the Audison Prima APS 10 S4S, which consists of water-repellent treated, pressed paper, has significant influences on the sound character. This design offers an ideal balance between stiffness and damping, enabling precise and dynamic bass reproduction. Thanks to the water-repellent properties, performance remains consistent even under humid conditions. The specific cone geometry, which was simulated using FEM and tested with the Klippel Scan Vibrometer, ensures improved displacement and sound quality.
